We know what the comedienne extraordinaire wants to do with the Biebster when she gets a hold of him … brush his bangs!

Tina Fey has the Bieber fever! When we caught up with the 30 Rock star at the NYC premiere of her new comedy, Date Night, Apr. 6, she couldn’t stop talking about teen pop sensation Justin Bieber! JB is set to perform on Saturday Night Live April 10, and Tina tells HollywoodLife.com EXCLUSIVELY that she can’t wait to get her hands on the little man! She even told us she wants to fix his bangs!

SNL alum Tina, 39, and host of the upcoming show even confesses that in addition to performing, the 16-year-old singer will even show off his acting chops in some sketches! Adds the comedienne, “I would love to do a sketch with him! I just hope the girls stop screaming long enough so we can do the sketches!”

By the sound of the Biebster’s April 8 tweet, there’s going to be a whole lot of singing, acting – and, yes – probably screaming. “Time for SNL rehearsal,” he wrote on his Twitter page. “Little singing little laughing.”

Cute screaming girls here!
